Private Sub Command1_Click() conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=" & App.Path & "\db1.mdb" rs.CursorLocation = adUseClient rs.Open "select * from t1", conn, 1, 3 Set DataGrid1.DataSource = rs DataGrid1.Refresh

End Sub 窗体上有datagrid 点击command按钮显示表中的内容 rs.CursorLocation = adUseClient要是不加这句话就不显示表中的结果 请问为什么要加这句话？什么意思？
